  example = m.top.findNode("instructLabel")

  examplerect = example.boundingRect()
  centerx = (1280 - examplerect.width) / 2
  centery = (720 - examplerect.height) / 2
  example.translation = [ centerx, centery ]

  m.top.setFocus(true)

I've encountered the same issue while trying to open one dialog from another, I managed to solve it by using a timer.

On my XML I've added

<Timer
      id="dialogTimer"
      repeat="false"
      duration="0.1"
/>

And on the first dialog click

m.top.dialog.close = true
m.dialogTimer = m.top.findNode("dialogTimer")
m.dialogTimer.control = "start"
m.dialogTimer.ObserveField("fire","showDialogTimer")

And then the function showDialogTimer handles the next dialog

sub showDialogTimer()
    showDialog()
end sub
